Synoposis:In 2029, Human Resistance leader John Connor (Jason Clarke) launches a massive final offensive against Skynet, an artificial general intelligence system seeking to eliminate the human race. Before the Resistance wins the offensive, Skynet activates a time machine and sends back a T-800 Terminator to 1984 to kill John’s mother, Sarah Connor (Emilia Clarke). John’s right-hand man, Kyle Reese (Jai Courtney), volunteers to travel back in time to protect her. As Kyle floats in the machine’s magnetic field, he witnesses John being attacked by another Resistance soldier. He then has visions from his childhood about events in 2017.Upon arrival in 1984, Skynet’s T-800 is disabled by Sarah and the Guardian (Arnold Schwarzenegger), a reprogrammed T-800 sent to protect her when she was nine years old. Kyle arrives a short time later and is immediately attacked by a T-1000 (Lee Byung-hun). Sarah and the Guardian join Kyle and destroy the T-1000 using acid. Sarah and the Guardian reveal they have constructed a makeshift time machine similar to Skynet’s, and that Sarah plans to travel to 1997 – the year Skynet becomes self-aware. Realizing the timeline has been altered, Kyle is convinced that the future has changed due to the warning he received in his childhood vision. He persuades Sarah to travel to 2017 instead to stop Skynet.
